Multichannel Fracturing Pump Connection for Continuous Well Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fracturing operations require operators to completely shut down one well before diverting high-pressure fluid to the next, increasing time and resource consumption.
Innovation Solution
A method and system for managing a multichannel fracturing pump connection that allows operators to prepare a second well for fracturing operations while continuing operations on a first well, using a conditional flow control valve and remote control system to enable seamless well swaps without shutting down the entire fracturing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators completely shut down one well before diverting high-pressure fluid to the next well, then well switching is achieved, but operational time and resource consumption increase
Solution Approach 1:
The system segments the well switching process into multiple independent valve operations. Instead of a single shutdown action, the patent implements a sequence of valve operations (master valve, flow control valve, and wellhead valve adjustments) that allow gradual transition of fluid flow between wells, enabling continuous pumping while switching targets.
Solution Approach 2:
The patent applies preliminary action by preparing the destination well in advance before fully diverting flow. The target well's valves are positioned and ready beforehand, and flow is gradually increased to the new well while simultaneously decreasing flow from the previous well, eliminating the need to wait for complete shutdown before starting new operations.
2Ease of operation
If operators completely shut down one well before diverting high-pressure fluid to the next well, then well switching is achieved, but resource consumption increases
Solution Approach 1:
The system maintains continuous useful action by keeping the high-pressure pumps running throughout the well switching process. The patent achieves this through coordinated valve operations that redirect fluid flow paths without interrupting pump operation, ensuring the pumps continuously perform their fracturing function across different wells.
3Productivity
If multiple well bores are fractured simultaneously, then productivity increases, but system complexity increases
Solution Approach 1:
The patent implements universality by designing a multichannel connection system where a single fracturing pump assembly can serve multiple well bores through a standardized valve and connection arrangement. The same pump system can be redirected to different wells through the valve network, making the equipment multi-functional and enabling sequential or simultaneous operation across multiple wells without requiring separate pump systems for each well.

AI summary
The present invention includes systems and methods for continuous fracturing operations across a multichannel fracturing configuration. To swap a first well for a second well while continuously pumping water and/or frac fluid through the fracturing system, the second well may be initially prepared through a pressure equalization process. Once the second well is equalized and open, the first well may be sequentially closed and depressurized. Thus, the first well is swapped for the second well while the water and/or frac fluid continuously flows through the system. A conditional flow control valve may be used to sequentially open and/or close the flow of frac fluid through the frac manifold.
